Decouple storage from the ZoneRuntime trait into a dedicated StorageEngine
trait with ZfsStorageEngine (illumos) and MockStorageEngine (testing)
implementations. Replace the per-zone ZfsConfig with a global
StoragePoolConfig that derives dataset hierarchy from a single --storage-pool
flag, with optional per-dataset overrides. This enables persistent volumes,
auto-created base datasets on startup, and a clean extension point for
future storage backends.

Implement an in-process broadcast event bus for resource mutations
(ADDED/MODIFIED/DELETED) with SSE watch endpoints on all list handlers,
following the Kubernetes watch protocol. Add the reddwarf-runtime crate
with a trait-based zone runtime abstraction targeting illumos zones,
including LX and custom reddwarf brand support, etherstub/direct VNIC
networking, ZFS dataset management, and a MockRuntime for testing on
non-illumos platforms.
